My understanding of the word ‘meme’ is that it is something reproduced and copied over and over within a community. That can refer to those questionairres OR to videos, images, and the like. Rickrolling or saying ‘DO NOT WANT’ are also memes. It’s a hard word to define, but I know one when I see one.

John and El are is right, a meme is any idea replicated (coined by Richard Dawkins in The Selfish Gene). An internet meme is any meme that happens on teh intertubes. Calling those questionnaires “memes”, which is a use I’ve mostly seen on Livejournal and the like, isn’t exactly wrong but it’s like calling Internet Explorer “The Internet”.

There is a difference between “meme” and “Blog Meme”. Even if we ignore the vacuity of the former in the field of cultural evolution, it has a much more broader meaning than the latter term, which is highly specific.
